Barometric slag-water separation system

Abstract

The invention discloses a barometric slag-water separation system. The system comprises a filter, a buffer tank and a dryer, wherein the top of the filter is provided with a vent pipe communicated with the outside, the upper part is provided with a purified water pipe for discharging purified water, the lower part is provided with a waste water pipe for introducing waste water, the bottom is provided with a slag-discharging pipe connected with the buffer tank, the waste water pipe is connected with a waste water discharge port through a water pump; the lower part of the buffer tank is provided with a slag-water pipe connected with the dryer; the cavity of the buffer tank is provided with a stirring rod extending lengthwise, the stirring rod is linked with a stirring motor arranged above the buffer tank; the dryer is divided into an upper part and a lower part, wherein the upper part is a hollow drying barrel with a lower opening, the lower part is a bowl-shaped strainer coated with a filter screen, the slag-water pipe is connected with the drying barrel; and the top of the drying barrel is provided with a squeezing pipe connected with a gas tank, and the bottom of the bowl-shaped strainer is provided with a discharge pipe for discharging water. By using the barometric slag-water separation system, the nonmetamorphic recovery of residues in waste water can be realized and the cyclic utilization of water resources can be better realized.

Description

technical field [0001] The invention relates to a wastewater treatment system, in particular to a pneumatic slag-water separation system. Background technique [0002] The stone processing industry needs to use a large amount of water resources to wash and cool the stone during the cutting process. This part of the water is mixed with the powder generated during the cutting process to form a large amount of waste water with residues. Although such residues such as stone powder and sludge are physically changing substances, if they are directly discharged into rivers, ponds and reservoirs without treatment, they will tightly seal the bottom of the water after sedimentation, and eventually cause severe water pollution by chemical changes. pollute. With the rapid development of the stone industry, the discharge of stone powder sludge is also increasing day by day, which has become a heavy burden for enterprises and society.

Problems solved by technology

The above scheme uses chemical methods to precipitate and separate the gravel from the water. Although it can save water resources, the gravel contained in the wastewater also forms non-recyclable waste residue due to the chemical action of the wastewater treatment agent, so it still cannot be used. Make good use of stone powder sludge and turn waste into treasure
